All time and zodiacal position data are computer
generated for the stations of Mercury in geocentric ecliptic longitude
(tropical zodiac) using Matrix's BLUE*STAR software, with nominal
precision to the nearest minute of arc. NOTE: BLUE*STAR uses 0 (zero)
for 1 BCE, and negative numbers for each year prior to that. Therefore
0 = 1 BCE, -1 = 2 BCE, etc.
